The base-of-the-pyramid (BoP) concept plays a prominent role among the market-based perspectives for poverty alleviation. Previous literature reviews discuss the evolution of the BoP concept as a research domain, but several major research streams that approach the phenomenon from distinct angles have been overlooked. To address these shortcomings, the authors expand these reviews and formulate recommendations for theoretical and empirical advances by considering emerging research domains, including corporate social responsibility, inclusive business, microfinance, nonprofit expansion, social entrepreneurship, and subsistence marketplaces. In revising the BoP business model idea, the authors develop a framework that highlights key dimensions for management research in BoP markets, including business ecosystems, financial viability, innovativeness, resource scarcity, role of the poor and scalability.
